SACRAMENTO, Calif. (KCRA) -

Threats and school evacuations continued Thursday in Tracy.

A Tracy Unified school -- the district spokeswoman couldn't say which -- received a phone call this afternoon, indicating a bomb was at Kimball High School. The caller specified a location where the alleged explosive could be found, as well.

At 1:35 p.m., the district contacted the Tracy Police Department and immediately evacuated its students from the threatened school to an adjacent football stadium at Kimball High.

Administrators dismissed the students at the normal time, which is 3:30 p.m. Several parents came early to pick up their children.

Bomb-sniffing dogs were then sent out to search the campus.

Meanwhile, one minute before Tracy High School was due for dismissal, someone found a bomb threat written on a wall in a boys restroom.

Students were notified of the threat over the school's PA system.

Officials said they didn't believe the threat was credible, students were told.

Still, staff members and teens were instructed to leave campus as soon as the final bell sounded.

Administrators then closed down the Tracy High campus for the day.

The district spokeswoman confirmed three Tracy High students were arrested for threats made Wednesday. She didn't release any names or specifics on those students.

District officials hope to find and prosecute all the people responsible for these ongoing threats and school disruptions, they said.

The district wants to remind teens that making these types of threats is a felony -- and students would be put up for immediate expulsion.
